What in the world is this? I dropped the pan due to poor oil pressure upon startup. Found the pickup tube loose. So, while it was down and out, I cleaned out the pan. What a mess. And in the bottom was this metal sleeve that almost looks like some sort of dowel pin. Its about 1/4 in tall and 1/4 in in diameter. I cant figure out what this is. Any ideas? Surely this isnt a valve guide. Im not having any valve train trouble. Picture is real good, but hopefully someone will be able to ID it.
